A common example of energy transfer that we see in everyday life is the transfer of kinetic energy —the energy associated with motion—from one moving object to a stationary object via work. In physics, work is a measure of energy transfer and refers to the force applied by an object over a distance.
A common example of energy transfer is the transfer of kinetic energy —the energy of motion—from a moving object to a stationary object. When a golf club is swung and hits a golf ball, some of the club's kinetic energy transfers to the ball.
A common example of energy moving between objects, called energy transfer, is the transfer of kinetic energy from a moving object to a motionless object. Kinetic energy is the energy of motion. When a bat hits a ball, some of the bat's kinetic energy moves to the ball. However, the energy stays in the same form.

Energy transformation happens when energy is converted into another form. There are many examples of energy transformations in our daily life. A toaster uses the electrical energy running through its wires to create thermal energy —heat—to toast a bagel.
Living things need energy to grow, breathe, reproduce, and move. Energy cannot be created from nothing, so it must be transferred through the ecosystem. The primary source of energy for almost every ecosystem on Earth is the sun.
Energy cannot be created or destroyed, but it can be transferred and transformed. There are a number of different ways energy can be changed, such as when potential energy becomes kinetic energy or when one object moves another object.
Some solar energy technologies include photovoltaic cells and panels, concentrated solar energy, and solar architecture. There are different ways of capturing solar radiation and converting it into usable energy.
In a difficult-to-digest nut shell, energy transfer through an ecosystem is restricted by the ability of primary producers to convert solar energy, and the ability of consumers to take in the energy they obtain as biomass.
These energy sources naturally renew, or replenish themselves. Wind, sunlight, and the planet have energy that transforms in ways we can see and feel. We can see and feel evidence of the transfer of energy from the sun to Earth in the sunlight shining on the ground and the warmth we feel when sunlight shines on our skin.
